Acoustic Phone Booth

Single-person acoustic phone booth on a 0.8x0.8m footprint at 2.2m tall, with a glazed door, felt-lined walls, a small perch shelf, a ceiling light and a top vent.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
